: Hi,

: I was just thinking about how we use wood as the filler between two layers of
: epoxy/glass, whereas racing kayaks tend to just be thicker glass (or
: kevlar or carbon fibre)covered in gelcoat, and so are really just a 'glass
: shell made in or over a mould. Stiffness coming from heavier glass rather
: than composite like strip/S&G.

: Then I wondered about making a kayak off another one. If exact dimensions
: weren't important (except the new one would be a small percentage bigger),
: would it be possible to cover an existing kayak with plastic wrap and then
: drape 'glass cloth over the hull and epoxy? Then do the same with the
: deck, cut out cockpit, etc and then join with 'glass tape? Then paint with
: gelcoat and viola, a close duplicate.

: Kind of like using the kayak as a male mould rather than building one in a
: female mould. Obviously a heavier glass would be needed to have stiffness,
: maybe with bulkheads and some other details.

: I'm not interested in copyright discussions about copying the hull - there's
: enough of those already! :-) - but just curious if anyone's done this or
: if it would work?

: Call it late-night kayak-builder's curiosity :-)

: Thanks,

It's called splashing a hull, since it actually has a name it of course works.

It's also stealing a design.
